Experiment 6. A cube of albumen of -^ of an inch and a piece 

 of gelatine of the same size as before were placed on a leaf, which 

 opened spontaneously after thirteen days. The albumen, which 

 was twice as thick as in the latter experiments, was too large; for 

 the glands in contact with it were injured and were dropping off; 

 a film also of albumen of a brown colour, matted with mould, was 

 left. All the gelatine was absorbed, and there was only a little 

 acid secretion left on the midrib. 



Experiment 7. A "bit of half roasted meat (not measured) and 

 a bit of gelatine were placed on the two ends of a leaf, which 

 opened spontaneously after eleven days; a vestige of the meat was 

 left, and the surface of the leaf was here blackened; the gelatine 

 had all disappeared. 



Experiment 8. A bit of half roaste<l meat (not measured) was 

 placed on a leaf which was forcibly kept open by a clip, so that 

 it was moistened with the secretion (very acid) only on its lower 

 surface. Nevertheless, after only 22* hrs. it was surprisingly soft- 

 ened, when compared with another bit of the same meat which 

 had been kept damp. 



Experiment 9. A cube of ^ of an inch of very compact roasted 

 beef was placed on a leaf, which opened spontaneously after twelve 

 days; so much feebly acid secretion was left on the leaf that it 

 trickled off. The meat was completely disintegrated, but not at 

 all dissolved; there was no mould. The little mass was placed 

 under the microscope; some of the fibrillce in the middle still ex- 

 hibited transverse striae; others showed not a vestige of stria:; 

 and every gradation could be traced between these two states. 

 Globules, apparently of fat, and some undigested fibro-elastic tissue 

 remained. The meat was thus in the same state as that formerly 

 described, which was half digested by Drosera. Here, again, as in 

 the case of albumen, the digestive process seems slower than in 

 Drosera. At the opposite end of the same leaf, a firmly compressed 



fellet of bread had been placed; this was completely disintegrated, 

 suppose, owing to the digestion of the gluten, but seemed very 

 little re<luced in bulk. 



Experiment 10. A cube of ^ of an inch of cheese and another 

 of albumen were placed at opposite ends of the same leaf. After 

 nine days the lobes opened spontaneously a little at the end en- 

 closing the cheese, but hardly any or none was dissolved, though 

 it was softened and surrounded by secretion. Two days subse- 

 quently the end with the albumen also opened spontaneously (i. e. 

 eleven days after it was put on), a mere trace in the blackened 

 and dry condition being left. 



Experiment tl. The same experiment with cheese and albumen 

 repeate<l on another and rather torpid leaf. The lobes at the end 

 with the cheese, after an interval of six days, opened spontaneously 

 a little; the culje of cheese was much softened, but not dissolved, 

 and but little, if at all reduced in size. Twelve hours afterwards 

 the end with the albumen opened, which now consisted of a large 

 drop of transparent, not acid, viscid fluid. 



Experiment 12. Same experiment as the two last, and here
